Hi Daniel
Nobody told me to do this. I just learned add-symbol-file from u-boot
document to relocate
program base. I tried some commands in gdb user's manual then I think this
command has result most
close to my expectation. Anyway, this is totally my fault.
I tried to follow your hint, shown as blow. Now, I can set a breakpoint in
the shared library and make
the program stop there. However, I still can not see the source code. (I am
using DDD with gdb.)
Am I still doing something wrong?
Thank you
Dennis
